Cortisol is a hormone naturally produced by your body. Created by the adrenal glands located on your kidneys, cortisol is released when you're under stress.

This sends your body into fight-or-flight mode, temporarily pausing regular bodily functions and slowing your metabolism.

Subsequently, this can cause weight gain, fat storage, and contribute to almost every age-related disease.

We all have stress to some degree. The secret is to manage your stress to maintain an effective, fat-burning metabolism.
